Log message:
    Add explicit tests for division by zero to all user-accessible integer
    division and modulo functions, to avoid problems on OS X (which fails to
    trap 0 divide at all) and Windows (which traps it in some bizarre
    nonstandard fashion).  Standardize on 'division by zero' as the one true
    spelling of this error message.  Add regression tests as suggested by
    Neil Conway.
